APT AWG 700 MHz Band Plan Development Process and timeline March 2008 - Spectrum Working Group initiated study of the UHF Digital Dividend, with the aim of developing a harmonized band plan Direct result of WRC-07 decision to identify spectrum for IMT
September 2010 - Finalized work on the new 700 MHz band plan(s) APT Report 14: Harmonized Frequency Arrangements for the Band 698-806 MHz Consensus Agreement
September 2011 - Finalized work on 2nd Report providing guidance on mobile user equipment outof-band emission levels to facilitate co-existence with adjacent band broadcast TV services APT Report 24: Implementation Issues Associated with Use of the Band 698 – 806 MHz by Mobile Services
Process was deliberate
Developed over 2.5 year period with considerable technical study by industry and governments Gathered views of APT members through information survey Prepared interim report with candidate band plan proposals – up to eight Focused technical studies on candidate band plans Set up technical correspondence group to work between meetings and analyze proposals Held technical seminars to further vet studies
High degree of cooperation among industry stakeholders (governments, vendors, operators, associations) was key

FDD band plan 2 x 45 MHz from 703-748 / 758-803 MHz – likely to require dual duplexer implementation Conventional duplex – minimizes harmonic interference into GNSS/GPS Internal guardband from 698-703 MHz and 803-806 MHz – facilitates co-existence with other services

APT Work is Complete Report 24: Implementation Issues Associated with Use of the Band 698 – 806 MHz by Mobile Services* APT Report 24 provides guidance on UE out-of-band emission levels: “Considering technical and economic factors associated with UE equipment, it was concluded that the average out of band emissions of IMT UE, measured over the bandwidth of the applicable television channel in the country of deployment, must not exceed -34 dBm/MHz below 694 MHz “
No guidance in Report 24 on the UE out-of-band emission levels from 694 MHz to 698 MHz. Instead, APT deferred any decision on this to the 3GPP standards development due to the technological advances in filter technology.

ITU-R Work on APT 700 MHz Band Plan is Complete Band allocated to the mobile service many years ago See Article 5 of the ITU Radio Regulations for Region 3
APT AWG 700 MHz band plan(s) were liaised from APT to the ITU-R ITU-R incorporated the new frequency arrangements into the most recent version of ITU-R Recommendation M.1036-4: “Frequency arrangements for implementation of the terrestrial component of International Mobile Telecommunications (IMT) in the bands identified for IMT in the Radio Regulations.” M.1036-4 formally approved in March 2012

3GPP Standardization of APT 700 MHz Band Plan(s) Band 28 (FDD 703-748 / 758 - 803 MHz) All CR’s (change requests) were agreed and work completed at RAN4 #63 meeting in Czech Republic May 21-25, 2012 Work item will be submitted for closure to the 3PP RAN4 Plenary this week in Slovenia (13-15 June 2012). Technical aspects: The 36.101 CR is in R4-123624 For co-existence with DTV service in 694-698 MHz adjacent bands, specified out-of-band emission level of - 26.2 dBm/6 MHz across 694-698 MHz and introduction of Network Signaled (NS) value Equivalent value to that recommended by APT at 694 MHz in dBm/MHz (-34 dBm/MHz)
Japan national issues – will resolve internally Self-band protection is defined at -32 dBm/MHz
3GPP members who supported work item include: Alcatel-Lucent, CATT, China Mobile, Ericsson, ETRI, HiSilicon, Huawei, KDDI, KT Corporation, LG Electronics Inc, LG-Ericsson Co., Ltd., Motorola Mobility, NII Holdings, Nokia, Nokia Siemens Networks, NTT DOCOMO, Qualcomm Inc., Samsung, ST-Ericsson, Telefónica S.A., Vodafone, ZTE

3GPP Standardization of APT 700 MHz Band Plan(s) Band 44 (TDD 703 – 803 MHz) All CR’s were agreed and work completed at RAN4 #63 meeting in Czech Republic May 21-25, 2012 Work item will be submitted for closure to the 3PP RAN4 Plenary this week in Slovenia (13-15 June 2012). Technical aspects: The 36.101 CR is in R4-123696 Emission limits to reduce the risk of harmonic interference into RNSS/GPS devices (inter-device coexistence) would not be specified in 36.101 but included in the Technical Report (TR) as a working assumption R4-123605
3GPP members who supported work item include: same list as Band 28
Not as much focus and attention on TDD studies as there was on FDD studies

Japan - Rhree pairs of 2 x 10 MHz in summer 2012 in accordance with APT FDD band plan Korea Allocated 2 x 20 MHz in accordance with the APT FDD band plan; usage of remaining spectrum officially not yet decided. Strong support for APT FDD band plan. Analog switch off complete by end-2012.
Papau New Guinea – Adopted APT FDD 2 x 45 MHz band plan Tonga - Adopted APT FDD 2 x 45 MHz band plan New Zealand Considering to auction in accordance with APT FDD 2 x 45 MHz band plan with spectrum rights commencing on December 1st, 2013. Official announcements on auction/timing expected soon
Taiwan Proposals tabled to auction in 2013/2014 in accordance with APT FDD 2 x 45 MHz band plan and assign to three 2 x 15 MHz licenses. Final decisions expected in 2012.
India Adopted National Frequency Allocation plan stipulating a requirement for IMT in 698-806 MHz; TRAI has proposed to auction in 2013 based on allocation of 2 x 45 MHz of spectrum for mobile

Observations and Recommendations APT 700 MHz FDD band plan represents best opportunity for Asia Pac regional spectrum harmonization Harmonized band plans deliver economies of scale which drive down device cost Opportunities for multi-regional harmonization APT 700 MHz FDD (full 2 x 45 MHz) potential for largest addressable market Design maximizes amount of usable spectrum for mobile services (2x45MHz) and is the most efficient use of scarce and valuable spectrum resources Momentum on APT 700 MHz FDD band plan is strong and increasing Operation of APT 700 MHz FDD (Band 28) together with extended-850 MHz (Band 27), 850 MHz (Band 5), 900 MHz (Band 8) provides a highly efficient use of spectrum resources below 1 GHz

Policy Support Needed From Governments Provide a roadmap with clear timelines for UHF Digital Dividend spectrum availability so that interested stakeholders have the certainty needed to plan networks and investments Make policy decision to allocate 698-806 MHz spectrum to the mobile service at the national level Make policy decision to harmonize frequency usage with the APT 700 MHz 2 x 45 MHz band plan Accelerate transition from analog to digital broadcast TV services in 700 MHz band which will free up the spectrum for its highest value use – mobile broadband Let industry stakeholders know how we can best support you in developing the regulatory and spectrum policy frameworks
